As an almost teenage mother I will give you my thoughts. but keep this in mind, think about how things use to be it was normal to get married and have kids at 15... some intersting facts.
1. every 2 years after age 17 you wait to have a child it increases the chances of defects.
2. during your teenage years you are more fertile, and Having a child balances hormones and things and reduces the risk of certain female problems
3. Name something that makes you grow up faster than knowing you are responsible for the life of someone else. the sole provider
4. I don't think we should be given handouts, it shouldnt be encouraged, but for those who do it for the fact they want a family they should have help.... Honestly no one is ever ready for a child, but some people want a family at a younger age, the younger you are the younger you will be for the grandkids...

5. Just because we are young, does not mean that we are dumb. true some of us have been raised with blinders but why is it that familys want to throw us out, churches disown us, and everyone look down and say slut becuase we decide we want a family rather it was planned or not?
America has lots of programs, government funding, (foodstamps, wellfare, college) most colleges have programs especialy if you go to teaching, or something with children, and many professors will tolerate young children in the room as long as they are quiet. Churches will sometimes offer daycare for younger mothers who routinly attend church...
just my two cents...
